Pressure-limiting device and method for supporting a pressure-limiting device.

摘要

The present invention relates to a pressure limiting device (10) with an inlet valve (22, 24, 26), which, in a first state, an inlet (14) with an outlet (18) and in a second state the inlet (14) against the outlet (18) which seals off, and a sealable pressure-relief connection (28, 30, 34, 44, 46), which in a sealed state of the outlet (18) against a pressure relief chamber (36) seals and in a sealed state the outlet (18) with the pressure relief chamber (36), the states of the inlet valve and a detachable sealing pressure-relief connection (28, 30, 34, 44, 46) of the position of the piston (20) depend. The movable piston (20) has a first active surface (38), which at the outlet by the pressure prevailing (18) is acted upon with a first force, and a second active surface (40) is oriented in opposite directions from the at the outlet (18) is substantially unaffected pressure prevailing.
